Rutledge explained what he was after. “I’m looking for anyone who might have been friends with a Captain Robert Burns who was at Saxwold in 1916. He was there for nearly a month, then was released to convalesce in London.”

“Ah, yes, I do recall Captain Burns. A very nice man. I heard much later that he’d returned to the Front and been killed. A waste.”

“Indeed. There was a woman, Eleanor Gray, who met him either in London or at Saxwold. Do you recall her?”

“I thought you wanted to know who among the wounded was friendly with him! I have no idea who Eleanor Gray is, Inspector. I had little time to waste on visitors. These were seriously wounded men in my care.”

“The problem is that I don’t know with any certainty whether Eleanor Gray introduced Captain Burns to the man I’m seeking or if she met him through Burns. If she met him through Burns, it might be someone he knew at Saxwold.”

“I understand now. Well, since I have no knowledge of this woman, I suggest we begin with the patients. There were a number of critically wounded men at Saxwold at the time, and they seldom mixed with the other patients. Certainly not often enough for a friendship to be formed. Therefore you must be interested in the men who were more or less able to move about or have visitors. If I remember correctly, there were at least twenty of those. Of them I would say that Captain Burns was friendly with three or four.”

She gave him names and told him how badly each was wounded. Three had lost limbs. Rutledge discounted them. Mrs. Raeburn had said she couldn’t tell how the man at her door had been wounded. The fourth had been blinded.

Trying to begin from another end of the puzzle, Rutledge asked, “Did you have patients from Palestine in Saxwold?”

“There was indeed one man who had served in Palestine. He’d been an intelligence officer, wounded, and sent home. Captured by the Turks, apparently, for he had been severely tortured. We feared more for his mind than his body, I must tell you that. He didn’t know who he was and he was by turns raving, silent, or alarmingly alert. Touch him and he was instantly back in captivity, striking out quick as a snake. We kept him in a room upstairs, under the eaves, where he didn’t disturb the other patients. Once Captain Burns could move about, he spent a good deal of time with the very ill, writing letters and so forth. The Captain made an effort to include Major Alexander in his rounds, though the stairs were difficult for a man with a serious back injury.”

“Alexander? Do you have a first name?”
